Qu’est-ce que les tests IoT ? Types et outils

What is IOT Testing?

Les tests IoT consistent à exécuter des tests d'assurance qualité pour vérifier la fonctionnalité, la sécurité et les performances des appareils IoT. Il est crucial de s'assurer que vos appareils IoT peuvent transmit sensitive information wirelessly before going to market because every IoT device sends and receives data over the Internet. Because of this, many IoT businesses rely on IoT automation, penetration, and performance testing tools to detect defects before reaching consumers.

IoT testing aims to ensure that IoT devices comply with specified requirements and work as expected.

What is Internet of Things?

The Internet of Things popularly known as IoT is the network that consists of devices, vehicles, buildings or any other connected electronic devices. This interconnection facilitates collection and exchange data. The 4 common components of an IoT system are

1. Sensor
2. Demande de leasing
3. Réseau
4. Backend (Data Center)

L'IOT est une connexion d'appareils embarqués identifiables avec l'infrastructure Internet existante. En termes simples, nous pouvons dire que l’IOT est une ère de produits connectés « intelligents » qui communiquent et transfèrent une grande quantité de données et les téléchargent vers le cloud.

Types of Testing in IOT

Testing for IOT devices broadly revolves around Security, Analytics, Device, Networks, Processors, Operating Systems, Platforms and Standards.

Let’s investigate the broad testing types

Usability Testing:

There are so many devices of different shape and form factors are used by the users. Moreover, the perception also varies from one user to other. That’s why checking usability of the system is very important in IoT testing.

Test de compatibilité :

There are lots of devices which can be connected though IOT system. These devices have varied software and hardware configuration. Therefore, the possible combination are huge. As a result, checking the compatibility in IOT system is important.

Reliability and Scalability Testing:

Reliability and Scalability is important for building an IOT test environment which involves simulation of sensors by utilizing virtualization tools and technologies.

Centres de données Integrity Test:

It’s important to check the Data integrity in IOT testing as it involves large amount of data and its application.

Tests de sécurité :

In the IOT environment, there are many users are accessing a massive amount of data. Thus, it is important to validate user via authentication, have data privacy controls as part of security testing.

Test de performance:

Performance testing is important to create strategic approach for developing and implementing an IOT testing plan.

Following chart gives applicability of different testing types for various components of IOT.

IOT Testing Process: Example Test Conditions

Challenges of IOT testing

• You need to check both the network and internal communication
• Security is a big concern in IOT platform as all the task are operated using via Internet.
• The complexity of the software and system may hide bug present in the IOT technology
• Resource considerations such as limitations in memory, processing power, bandwidth, battery life, etc.

Meilleur practices for effective IOT software testing

• Gris Box vers les tests should be used with IOT testing as it allows to design effective test case. This allows you to know the OS, the architecture, third-party hardware, new connectivity and hardware device limitation.
• Temps réel Operating système is vital to delivering the scalability, modularity, connectivity, security, which is important for IOT
• IoT Testing should be automated.

IOT Testing Tools

Les deux outils de test IOT les plus efficaces sont :

1.Shodan

Shodan is an IOT testing tool which you can use to discover which of your devices are connected to the Internet. It allows you to keep track of all the computers which are directly accessible from the Internet.

2. Thingful

Thingful is a search engine for the Internet of Things. It allows secure interoperability between millions of objects via the Internet. This IOT testing tool also to control how data is used and empowers to take more decisive and valuable decisions.

Conclusion

• IOT is a connection of identifiable embedded devices with the existing Internet infrastructure.
• The complexity of the software and system may hide bug present in the IOT technology
• Gris Box testing should be used with IOT testing as it allows to design effective test case.
• IoT Testing ensures that the users get the improved user experience across all the connected IOT devices.
• As there is no test plan, part of the properties to be tested cannot be measured. So, errors/bugs may not be detected easily.
